Melt pump and screen changer

Product introduction

Melt pump is used on extruder for transporting and metering high temperature and viscosity polymer melt ; at the same time, pressurize and stabilize the pressure of material from extruder then transport to die. Its capacity of stabilizing and metering kinds of plastics is better than kinds of extrusion. Melt pump also called metering pump, extrusion pump, extruder gear pump, it is widely used in extrusion molding in plastic, resin, rubber industry. Now granulation, film, pipe, plate, sheet, and other industries; melt pump is the essential part of extrusion equipment, applied in PP, PS, PET, PVC, ABS, PE, PA, rubber, and etc.

Product characteristics

1, can be applied to high temperature (350℃) high pressure (35MPa) high viscosity (20,000Pa•s) working conditions;
2, optimized channel design, avoid dead corners in the channel, reduce material residues, improve product quality.
3, improved gear parameter design, so that the output pressure is more stable, lower pulsation rate, suitable for precision extrusion.
4, using high temperature alloy steel, good wear resistance, long life.
5, using different sealing methods to adapt to a wide range of viscosity. 6, according to the customer's different site conditions to provide the appropriate installation method, more flexible and practical.
